RFI for MAGIS-100 Suspended Work Platform System

Request for Information (RFI)

This RFI seeks information from vendors capable of designing, fabricating, and potentially assembling and installing a suspended work platform system for the MAGIS-100 experiment at Fermilab. The system is needed to provide safe access to instrumentation within a 100m deep vertical shaft. This RFI is for informational purposes only and does not constitute a subcontract award. Responses will be used for planning purposes and to inform a future Request for Proposals (RFP).

Vendors are requested to provide:

• A sketch, drawing, or model of a suspended scaffold design aligning with the attached SOW.

• A budgetary cost estimate and lead time for scaffolding parts.

• A description of the assembly and installation procedure.

• Examples of previous relevant work.

• Design recommendations and proposed adjustments.

• This RFI is for informational purposes; no subcontract will be awarded.

• Participation does not commit FFDG or the US Government to pay costs or imply preference for future subcontracts.

• Responses are due by July 14, 2026, at 5:00 PM CT.

• All questions should be submitted via email to damico@fnal.gov by July 2, 2026.

• A virtual pre-RFI meeting is scheduled for June 25, 2026.

• Submissions should be sent via email.

Not specified in this RFI.

• The MAGIS-100 experiment involves instrumentation in a 100m deep shaft.
• Access methods for different platform depths include ladders, suspended scaffolds, and scissor lifts.
• Fermilab has developed a stabilizer assembly for securing platforms.
• Attached documents include a Draft Statement of Work and the MAGIS-100 Experiment Poster.

Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the requirements for a suspended work platform system for personnel to safely access regions of the MAGIS-100 experiment within a vertical shaft at Fermi National Accelerator Laboratory (Fermilab).

• Design and provision of a moveable scaffold system for a 100m deep shaft.

• Platforms will provide access to instrumentation for maintenance.

• Access methods vary by shaft depth: ladders from the ground floor (top 26ft), suspended scaffold/access basket (middle), and scissor lift (bottom 32.5ft).

• A stabilizer assembly will be used to secure the scaffold/basket to platforms.

• Moveable scaffold dimensions: approximately 64" deep x 68" wide.

• Extension capability to reach areas 40" from nominal access position.

• Scaffold must have sufficient tie-off points.

• Work area must have a roof to deflect falling objects.

• Scaffold must stow outside the shaft region, ideally above crane operating height.

• Scaffold load rating: at least 4 times the maximum intended load of 2000 LB (i.e., > 8,000 lb).

• Flat wall cannot be used for structural support.

• Equipped with 2" square railing at 41" +/-1" height for compatibility with stabilizer system.

• Scaffold must be stable for mechanical assembly tasks (e.g., torquing bolts to 200ft-lbs) without hazardous movement.

• Platform must support a 500 LB point load at any location.

• All designs must adhere to OSHA and other applicable requirements.

• The project is in the Preliminary Design phase, with anticipated procurement near the end of 2026.

• The work is to be performed at Fermilab.

• Vendors must demonstrate capabilities to meet the specific requirements outlined.

• Reference to Figures 1-6 for visual context of the shaft, experiment, and platform examples.
